Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
MG6206K3B-33 from Megain, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground terminal of the regulator (接地端); the datasheet gives no separate electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated output voltage pin; for the MG6206K3B-33 the nominal output is 3.3 V with ±2% accuracy and up to 300 mA output current. |
| 3 | VIN | power_in | Input voltage pin; recommended VIN is 3.2 V to 6 V, and the absolute maximum rating is -0.3 V to +8 V. |
